Moldova.ORG -- A major earthquake occurred about 525 km (325 miles) ENE of Kuril'sk, Kuril Islands of Russia or about 1710 km (1060 miles) NE of TOKYO, Japan at 10:23 PM MDT, Jan 12, 2007 (Jan 13 at 2:23 PM local time in Russia).

The Japanese meteorological agency initially estimated the magnitude as 8.3 but later reduced that to 8.2, the same strength recorded by the U.S. Geological Survey (USGS). The quake struck 19 miles below the seabed.

No reports of damage or casualties have been reported yet, but this earthquake may have caused damage due to its size.

Earthquakes of this type sometimes cause tsunamis, however the USGS has no information that an actual tsunami has been generated.

Japan issued a tsunami warning and urged coastal residents to head to higher ground agency. Waves as high as one meter (three feet) were expected to reach the coast of northern Hokkaido around 2:00 pm (0500 GMT) and also to hit the Pacific coast on the main island of Honshu, the Japanese meteorological agency reported.

A tsunami warning was issued for northern Japan, Russia and a wide swathe of Japan's Pacific coast on Saturday.

According to the US West Coast and Alaska Tsunami Warning Center (http://tsunami.gov/), the Tsunami Warning and Watch are canceled for British Columbia and Alaska, since no destructive tsunami threat exists fort he Western coast. However, some areas may experience observable effects which could include strong currents in harbors and bays dangerous to those in or near the water. These effects are expected to begin at approximately 0440AM PST in the Pacific Northwest ranging to 0600AM PST in southern California and could continue for several hours after initial arrival.

The Pacific Tsunami Warning Center withdrew a tsunami watch for a vast part of the Pacific basin including the Philippines, Vietnam, Indonesia, Papua-New Guinea, and Hawaii.
